Vitali Klitschko has refused to speculate on his future and revealed he would not make a decision before the end of the year.

Klitschko, who retained his WBC heavyweight belt against Manuel Charr in September, says he will announce in the New Year whether he intends to fight again or hang up his gloves in order to focus on his political career.

"I don't know what's going on with my sports career," Klitschko was quoted as saying by Boxing Scene. "I'm not ready to give you an answer.

"I enjoy boxing very much. I like boxing very much. When I'm in training camp, I enjoy every minute of training camp."

Klitschko, leader of Ukrainian opposition political party UDAR, has been linked with British fighter Tyson Fury.
